Hi!

So recently I've realized that I might have SAD. Round the winter solstice, there's about 6 hours of sunlight per day in Estonia and for much of December and early to mid January, it was also overcast so even the 6 hours of "sunlight" were kinda dark.

So I went to read Wikipedia and:

Two methods of light therapy, bright light and dawn simulation, have similar success rates in the treatment of SAD

So I'm just wondering if anyone has personal experiences with these, particularly the dawn simulation as I believe that's something I could just set up and forget hopefully (I have ADHD, I do NOT do well with things I have to repeat every day). Does it help? Do you use it outside of wintertime too?

For some reason or another, a whole third of all mechanical keyboards in the biggest local computer retailer's online store, are Ducky. Probably because they have ISO and ANSI layouts, a lot of colors, different sizes, and different switches. And they're ordered from abroad when bought, not stocked locally. So loads of choice and no cost showing them as available.

So since my only real options here if I want a full keyboard or TKL with blue switches are a couple of different Ducky models (one 3, Shine 7) in various colors, I'm wondering if anyone has personal experience with Ducky? I've read both praise and hate online, so can't really make heads or tails of the quality.

Long story short, despite living in a detached home with not too much 2.4 GHz noise, my Logitech unifying receiver has trouble with my mouse at 20 centimeters from the receiver. Keyboard at roughly 7-8 centimeters range has less trouble, but not none.

I can't be arsed to get an USB extension cord or anything. This is a stupid-ass problem. I want to replace them with something new. What mouse would you suggest that's ergonomic, but not too expensive? I'd say 150€ is the absolute limit, but would prefer under 100€. Mouse should be wireless as I have a tendency of moving it around. It's just the Unifying Receiver tripping me up - I've not had much trouble with other wireless mice in the past, and the same mouse works completely fine on Bluetooth as far as range is concerned, but it's a pain to reconnect on Linux for some reason or another.

I do a little gaming, but mostly software engineering. Precision isn't as important as comfort. I also don't want to get something uber weird shaped, it should still look and feel like a mouse ideally.
